Running R27 Reivision 1.0.
Sudo apt-get update has errors:
W: Invalid ‘Date’ entry in Release file /var/lib/apt/lists/_var_nv-gie-repo-ga-cuda8.0-gie1.0-20170116_Release
W: GPG error: file:/var/libopencv4tegra-repo Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY D88C3D385C37D3BE
W: The repository ‘file:/var/libopencv4tegra-repo Release’ is not signed.
N: Data from such a repository can’t be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
W: Invalid ‘Date’ entry in Release file /var/lib/apt/lists/_var_libopencv4tegra-repo_Release
Looks like two of them: an invalid date and an unsigned repo. How do I fix this?
